A USB device is active 100.0% of the time:
/sys/bus/usb/devices/1-6

Suggestion: Enable USB autosuspend by pressing the U key or adding 
usbcore.autosuspend=1 to the kernel command line in the grub config

Suggestion: Enable SATA ALPM link power management via: 
  echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
or press the S key.

Suggestion: Enable laptop-mode by executing the following command:
   echo 5 > /proc/sys/vm/laptop_mode
